Didn't read the whole thread so sorry if this has been done...

You don’t need a join, you can just use criteria if you like (not
necessarilly very eficient though?)

E.g. "SELECT a.*, b.* FROM a, b WHERE a.col1=mid(b.col2,3)"

Thank you all for the comments.

That is exactly what I ended up doing.  But since I lack the SQL "guru"
certification ;) I thought I'd put the question out there.  I was
thinking back to a thread a long while back regarding a method that
creates a sort of temporary table within one query...or something along
those lines.  I didn't know if/how that method might apply to my
situation.

Hi Mark and Arthur

That may work but you'll be in trouble when trying to switch to design
view. I would create a query for Tbl2 with a field with the expression
needed to match the Tbl1.Fld1. Then use this query for Tbl1 whenever you
need to join Tbl1 and Tbl2.
